 ## Building and flashing the firmware
 
-For the left keyboard half, make sure to power it via the right keyboard half (which must be powered via USB). Also connect the left keyboard half to your SEGGER J-Link USB debug probe (which must also be connected via USB). Then in KDS, click on *Run -> Run Configurations*, select *GDB SEGGER J-Link Debugging -> uhk-left release jlink*, and click on the *Debug* button.

Then in KDS, click on *Run -> Run Configurations*, select *C/C++ Application -> uhk-right release blhost*, and click on the *Debug* button. Please note that this update method only works on Linux out of the box. On other operating systems, you have to execute the relevant commands of the [blhost-unix.sh](right/build/kds/blhost-unix.sh) script.
+For the right keyboard half, flash [the bootloader](https://github.com/UltimateHackingKeyboard/bootloader) first.
+
+At this point, you can flash the right firmware via USB from KDS. To achieve this, you must build [Agent](https://github.com/UltimateHackingKeyboard/agent) that is Git submodule of the this repo and located in the `lib/agent` directory.  Then in KDS, click on *Run -> Run Configurations*, select *C/C++ Application -> uhk60-right_release_kboot*, and click on the *Run* button.
+
+From this point on, you can upgrade the firmwares of both halves via USB by using the uhk60-left_release_kboot and uhk60-right_release_kboot run configurations. Alternatively, you can use your SEGGER J-Link probe.
